Removed tag 0.1

Added tag 0.1 for changeset d4ce82194b64

- 1st pass at documentation with the README. - Attempt to detect trivial redirect loops. - Loosen the request parser enough to just accept URLs, so you can easily test rewrite behavior by just running volta and pasting URLs. - Alter the whitelist "negative" rule syntax to more closely match normal rules. Rename references to negative rules from "whitelist" rules, to avoid confusion.

Retain the CDB struct between lookups, only freeing when reopening the db. Big, big speed boost.
